Ni/CeO2基催化剂构筑及其CO2甲烷化催化性能研究进展
Research progress on construction of Ni/CeO2-based catalysts and their catalytic performances of CO2 methanation
摘要
Abstract
CO2 hydrogenation to methane(also known as"CO2 methanation")is an important way to achieve the goal of carbon neutralization.CeO2 is considered as one of the most important catalyst supports because of its abundant surface oxygen vacancies and excellent oxygen storage capacity.Transition metal Ni is also widely studied because of its excellent catalytic performance and low price.The Ni/CeO2-based catalysts formed by the combination of CeO2 and metal Ni show good application prospects in CO2 methanation.The reaction mechanisms of Ni/CeO2-based catalysts for CO2 methanation were summarized and the preparation methods of Ni/CeO2-based catalysts were introduced,and the key parameters affecting catalytic performance of CO2 methanation such as the characteristics of active centers,properties of supports,types of additives and metal-support interactions were summarized,and the catalytic performances of Ni/CeO2-based catalysts were also summarized.It is found that by modifying Ni/CeO2-based catalysts,the catalytic performances and product selectivities of Ni/CeO2-based catalysts for CO2 methanation can be regulated,which can provide new ideas for improving their catalytic performances of CO2 methanation.关键词
